Qlab fade video2/28/2023 The center section of the Geometry tab contains controls for the fade-able parameters of a Video, Camera, or Text cue. This button provides quick access and a visual reference to the live fade preview setting. Relative fades are discussed in detail below. This drop-down menu lets you choose between an absolute fade, which is QLab’s default, and a relative fade. If the box is unchecked, the target cue will continue to run after the fade is complete.Ībsolute Fade. If this box is checked, the target cue will stop once the fade is complete. This is a convenient way to get started building a fade, as it will help you keep track of the starting point from which you will be fading. You can choose other properties if you like, but if you simply hit the enter key, QLab will paste the geometry from the target cue onto the Fade cue. First, it will behave as though the target cue was selected and copied, and second it will automatically select the “Video” set of properties to paste. The left side of the Geometry tab contains a few setup tools:Ĭlicking the Set Geometry from Target button, or using the keyboard shortcut ⌃⌥⌘V, will invoke the paste cue properties sheet in a special way. The Geometry tab allows you to specify which parameters of the target cue you wish to fade, and what their final value will be. It behaves the same as the Levels tab for Fade cues targeting Audio cues. The Levels tab will only appear if the target cue contains audio. You can learn about this control from the Fading Audio section of this manual. The Audio Domain pop-up menu is only relevant if the target cue contains audio and if anything pertaining to audio is being faded. To start over entirely, click Reset to Default Shape in the bottom left corner of the tab.īoth the rising and the falling curve use the same fade shape type, but if you use custom curve or linear curve you can create individual curve shapes for each. To delete a control point, click on it to select it and press the delete key on your keyboard. This option is similar to the custom curve option but instead of smoothly ending the curve, control points create a precise, sharp bend. This option adds a text field labeled Intensity below the pop-up menu which allows you to use a mathematically precise parametric fade shape. To start over entirely, click Reset to Default Shape in the bottom left corner of the tab. Moving control points will smoothly bend the curve in the direction of the control point. This option allows you to click anywhere along the fade curve and a create control points, which can be dragged to change the shape of the curve. QLab’s default curve shape follows an “ease-in, ease-out” envelope designed to sound natural with audio levels and look smooth with video geometry. There are four options for Fade curve shapes: The curve shape that appears by default is set according to the Fade cue’s cue template, but you can choose another fade shape from the pop-up menu in the top left corner of the tab. For the rising curve, the one of the left, the bottom left corner represents the beginning of the fade, which is to say “time = 0, completion = 0%.” The top right corner represents the end of the fade, or “time = (duration of the Fade cue), completion = 100%.” For the falling curve, the top left corner represents the beginning and the bottom right corner represents the end. The vertical axis represents percentage of the total change made by the Fade cue. The horizontal axis of the curve represents time and the labels across the top will change based on the duration of the Fade cue. The curve on the left is for levels which increased by the fade, and the curve on the right is for levels which are decreased by the fade. The fade curve, drawn in yellow on the right side of the tab, determines the rate of change of the parameters being faded. When a Fade cue which targets a Video cue or Camera cue is selected, the inspector shows the Basics tab and Triggers tab, used by all cues, as well as the following tabs: The Curve Tab The word “fade” can often be taken to mean one thing or another, but in QLab “fade” simply means “change a value over time.”įade cues require a cue target, have a duration, and must adjust at least one level or parameter of their cue target in order to be considered functional. When a Fade cue is selected, the inspector will only show the tabs relevant to the type of cue that the Fade cue is targeting. Fade cues can also adjust audio parameters of Video and Camera cues. The Fading Video tutorial is a hands-on exploration of the topics discussed in this section.Ī Fade cue can be used to adjust the geometry and video effect parameters of a targeted Video, Camera, or Text cue.
